Question 1

How much should I spend on Google Ads for ecommerce?

Accepted Answer

Work backwards from your revenue goal: Revenue Goal ÷ AOV = Orders Needed ÷ Conversion Rate = Clicks Needed × CPC = Budget. For Shopping campaigns at $0.80 CPC and 2% CVR with a $15,000 goal: 231 orders ÷ 2% = 11,538 clicks × $0.80 = $9,231/month. This calculator does the math for you.

Question 2

What is a good CPC for Google Shopping ads?

Accepted Answer

Average Google Shopping CPC ranges from $0.30-$1.50 depending on product category and competition. Fashion: $0.30-$0.80. Home & Garden: $0.40-$1.00. Electronics: $0.60-$1.50. Performance Max campaigns often achieve lower CPCs through automated placement optimization.

Question 3

Google Shopping vs Search Ads — which is better for Shopify?

Accepted Answer

Shopping/PMax typically delivers better ROAS for product-based businesses because of lower CPCs ($0.30-$1.50 vs $1-$5 for Search) and higher purchase intent from visual product ads. Search ads work well for branded terms and high-intent queries. Most Shopify stores should start with Shopping/PMax and add Search for brand defense.

Question 4

What ROAS should I target on Google Ads?

Accepted Answer

Target ROAS depends on margins. With 60% gross margin, 2x ROAS breaks even. Most Shopify stores target 4x-8x ROAS on Google Shopping and 3x-5x on Search. Brand campaigns often achieve 10x+ ROAS. This calculator shows your break-even CPC — the max you can pay per click at your target ROAS.

Question 5

What is a good conversion rate for Google Ads?

Accepted Answer

Ecommerce averages: Search ads 2-5%, Shopping/PMax 1-3%, Display 0.3-1%, Brand search 5-10%+. Conversion rate depends heavily on landing page quality, price competitiveness, and product-keyword match. Improving CVR by 1% can reduce your required budget by 30-50%.
